Ankle anatomy normal ap mortise the weight bearing portion is formed by the tibial plafond and the talar dome the joint extends into the lateral gutter 1 and the medial gutter 2 the joint is evenly spaced throughout.
Medial gutter ankle anatomy.
The talus is wedge shaped wider anteriorly by 2 5 mm and the talar dome is trapezoidal.
Typically the capsule and synovial lining of the ankle joint get inflamed and can develop scar tissue in either the anteromedial gutter or anterolateral gutter between the ankle bones.
The anterolateral ankle gutter is the most common site of ankle impingement.
It causes pain on the inside of the ankle which is exacerbated by activity especially running and jumping activities.
Bony proliferation and osteophytic spurs can be seen at the anteromedial tibial plafond and at the medial malleolus 1 which can be better seen on lateral ankle radiograph or sagittal view on ct.
The medial ankle causing medial gutter impingement due to overstress of the deltoid ligament or due to components not adequately covering the resected portion of bone 8 medial gutter impingement was more common than lateral in our study but both were.
A stress fracture of the medial malleolus can occur but is very rare 2.
The lateral gutter of the ankle joint c can be found by running the thumb medially over the anterior and medial edge of the fibula.
Ankle anatomy the ankle is a complex hinge with articulations between the tibia fibula and talus forming a mortise joint.
This irritation and hypertrophy of the tissue can cause pain with ankle dorsiflexion and subsequently symptoms with athletic activities.
The medial malleolus is the bony bit on the inside of the ankle.
The ankle arthroscopic procedure without distraction allows constant visualisation of the atfl s superior fascicle on the floor of the lateral gutter the atifl s distal fascicle laterally and the most anterior margin of the deltoid ligament in the medial gutter anterior tibiotalar ligament.
The knee should be placed in flexion of approximately 20 to 30 and the valgus force applied to open up the medial compartment.
Inspection of the medial compartment is performed with the knee slightly flexed to allow the scope to enter the compartment over the anterior horn of the medial meniscus.
